highly significantP < 1.7×10 −7
For each parameter and across the 1000 parameter sets, f del shows a highly significant correlation to S , but one that is only modest in value for some parameters (Spearman’s R = 0.16–0.76, P < 1.7×10 −7 , n = 1000 for all parameters), illustrating that S cannot generally substitute as a measure of f del .
